T形钢管混凝土柱-钢梁平面框架抗震性能研究
Experimental research on seismic behavior of concrete filled T-section steel tube columns and steel beam planar frames
摘要
Abstract
To research the seismic behavior of concrete filled T-section steel tube columns and steel beam frames,two specimens were tested by quasi-static test.The influence of axial compression ratio on the frame hysteretic behavior was discussed.The experimental results show that the beam-hinge failure mechanism is realized.With the increase of horizontal load,the hysteretic curves of frames become fuller and fuller.The displacement ductility coefficients in two loading directions are above 4.0,which satisfies the seismic design requirement of building structure.Axial compression ratio is the major factor that affects frame seismic behavior.The higher the axial compression ratio is,the greater the energy dissipation capacity is,but the displacement ductility of the frame is reduced.A simple tri-linear restoring force model was proposed,which could provide the reference for the application of the concrete filled T section steel tube columns and steel beam frame in engineering.关键词
